About Shadow Snap
Created by Ward Lu and Shadow Lab, Shadow Snap helps film fans, writers, and content creators turn a single movie still and multiple dialogue lines into a cinematic long subtitle image. When a line deserves more than a plain screenshot, upload the image and type the words: Shadow Snap keeps the first frame intact, then joins slices of the lower subtitle region beneath it so the whole dialogue reads as one continuous scene.
Key Features
- Keep the frame connected: Keep the first frame intact and stitch the following subtitle slices automatically as the dialogue grows, line by line.
- Write first, let the layout follow: Press Enter to create a new subtitle slice. Choose Chinese (Noto Sans SC), Latin (Roboto), Monospace (IBM Plex Mono), Thai (Noto Sans Thai), Vietnamese (Noto Sans Vietnamese), and Arabic (Noto Sans Arabic) fonts.
- Typography and framing controls: Use built-in film color presets (Nolan White, Wong Kar-wai Gold, Tokyo Cyan, Minimal Mono) or customize font size, text color, outline color, slice height, and safe margin.
- Add a signature when you share: Enable a custom watermark and adjust its text, position (Bottom Right, Bottom Left, Top Right, Top Left, or Center), opacity, font size, and color before exporting.
- Keep the image in your browser: Process and export images locally with HTML5 Canvas without uploading your photos to a server. Free to use in your browser without an account or installation.
Make a Subtitle Image in Three Steps
- Import a movie still or video screenshot in JPG, PNG, or WebP format.
- Enter your dialogue, using a new line for each subtitle slice.
- Adjust the font, slice height, and watermark, then select Export Image.
Common Use Cases
- Share a line on social media: Turn a film quote, book excerpt, or your own words into a vertical post that carries the scene with it.
- Build promo visuals with atmosphere: Create a cinematic asset from a single still and a few lines without opening a full design suite.
- Give everyday photos a voice: Add dialogue to travel, daily-life, or creative photos so they say more than they show.
